BUCKET ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 578,221, dated March 2,1897. Application filed September 3,1895- Serial No. 561,292. (Nomodel.)

.To all whom it may concern.-

Be it known that I, JAMES M. DODGE, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Bucket Elevators, of which the following is aspecification.

The object of my invention is to dispense with the chain-links usuallyemployed in the construction of bucket elevators; and this object Iattain by coupling the buckets together directly, as fully describedhereinafter, reference being had to the accompanying drawings, in which-Figure 1 is a perspective view of one of my improved buckets. Fig. 2 isa front elevation showing two buckets coupled together. Fig. 3 is a sideview of Fig. 2. Fig. i is a section on the line 4 4, Fig. 2. Fig. 5 is aplan view. Fig. 6 is a detached perspective view of one of the sidebraces. Figs. 7 and 8 are views of modifications of myinvention, andFig. 9 is a view of one of the side braces before bending.

Heretofore in the manufacture of elevatorbuckets it has been customaryto build a chain of a series of links and to secure the buckets tocertain of these links, the elevator having either a single run of chainor a double run, according to the method of attaching the buckets to thechains.

By my invention I dispense entirely with the independent links andcouple the buckets directly one to another, as illustrated in thedrawings.

A is a bucket, in the present instance havin g a back wall a, frontincline wall a, and side walls a but it will be understood that theshape of the buckets may vary without departing from the essentialfeature of my invention. Secured at the corners formed by the back andside walls are angle-plates B, one at each side. The leaf 1) of eachangleplate is secured to the side walls a of the bucket by rivets orother fastenings, and the leaf 1) of each plate is secured in a likemanner to the back wall a. Thus the. angle-plates form strengtheningmembers of the bucket.

The plates B B extend beyond the bucket both above and below, asindicated in Figs. 1 and 3, and by preference the leaf b is cut somedistance from each end, forming portions 12 which are bent over upon theprojecting portion of the leaf Z). These end portions of the plate areperforated for the passage of the pivot-bars 0, so that the end portionsof the plate act as hinge-pintles.

The bars 0, as shown clearly in Figs. 2 and 5, are simply sections ofplain rods reduced slightly in diameter at the points where the bucketshinge, so as to form shoulders which prevent the bar from beingaccidentally detached, but this construction may be modified, ifdesired.

The perforations in the buckets for the pivoted bars are of the samediameter as the main portion of the bars, so that the bars can beslipped in place and the slight reduction of the bars is not sufficientto interfere with the proper working of the elevator, but will preventthe lateral displacement of the bars.

The back plate of each bucket extends above the top of the bucket,forming a shield a which prevents th e material accumulating between thetop of the bucket and the pivotbar C when the buckets are beingdischarged.

It will be seen by bending the sections 19 and 5 onto the portion 1) ofthe angle-plate B that I increase the bearing-surface of the buckets andthus extend the life of the pivotbars without materially increasing thecost of construction.

The pivot-bar may be reduced to form the groove by turning or the groovemay be formed by compression, as a very small shoulder is required toprevent the accidental displacement of the pin.

In some instances the extension may be formed directly on the plates ofthe bucket, and I have shown in Fig. 7 one form where the bearings aresimply extensions of the back plate, the plate being cut and bent asindicated.

In some instances the project-ions may be on one end only of each bucketand the pivotbar may pass through the projections and through thebucket, as shown in Fig. 8, but I prefer the construction shown in Fig.1.

I claim as my invention- 1. The combination in an elevator-bucket, ofthe body, perforated projections at each side and extending above andbelow the body,

said projections being increased in thickness at the perforations,substantially as and for the purpose set forth.

2. The combination in an elevator-bucket, of the body, the angle-platessecured at the corners formed by the back and sides of the body andextending above and below the bucket, substantially as described.

3. The combination in an elevator-bucket, of the body, an gle-plates atthe corners formed by the back and sides of the body, said angleplatesextending above and below the body, and a portion of the back section oneach angle-plate being bent over upon the side portion so as to form adouble bearing for the pivot-bars, substantially as described.
